Evaluation Board Hardware Description
5.
START3
- Provides start signal for Injector 3
6.
START4
- Provides start signal for Injector 4
7.
START5
- Provides start signal for Fuel Pump 1
8.
START6
- Provides start signal for Fuel Pump 2
9.
DBG
- Provides the trace signal if activated
These nine signals are provided by the nine parallel outputs from the USB/SPI interface, as described by
the following:
1.
DRVEN
- Connected to the DATA0 signal
2.
RESETB
- Connected to the DATA1 signal
3.
START1
- Connected to the DATA2 signal
4.
START2
- Connected to the DATA3 signal
5.
START3
- Connected to the DATA4 signal
6.
START4
- Connected to the CNTL0 signal
7.
START5
- Connected to the CNTL1 signal
8.
START6
- Connected to the CNTL2 signal
9.
DBG_EXT2
- Connected to the CNTL3 signal
DATA0 - DATA4 and CNTL0 - CNTL3 signals are logic level outputs from the USB/SPI dongle that can
be controlled directly from the SPIGen program. An example SPIGEN configuration file called
KIT33816SW.spi is provided in the software bundle, which contains several batch file examples.
If the user prefers to supply the various MC33816 input signals externally, other than from the USB-SPI
interface, the connections are available on the connector listed by the following.
11.4
USB/SPI Dongle Connector
The USB/SPI dongle connector is a 16 pin, 0.1” center, dual-row connector that is designed to interface
directly to the USB/SPI dongle unit. The USB/SPI dongle connector consists of the following 16 pins.
